ANTIRAQTLING DEVICE.

Application filed March 29, 1923. Serial No. 628,404.

ing tortional strain preventing the same from rattling. It also places the roll-back coupled with the Outside handle, under a yielding stress and voids chattering of-this member. It is not'broadly new to place a retracting lever under spring stress to take up any lost motion to prevent rattling. This is quite a common expedient in vehicle locks. Our ,improvement consists in applying the spring stress to .the outside handle splndle so as to put the handle under yielding stress where it enters the hole of the rollback to takeiup any looseness there and also to put the roll-back under stressto prevent the same from chattering against the bolt or against the roll-back stop.

A further improvement is the arrangement of the telescoping cups whereby the spring may be easily and quickly coupled up to the stationary door parts and the turning handle spindle. This will more fully appear in the description following.

In the drawings: 1

g designates the usual lock casing in which is slidably guided the bolt 6, having an upwardly extending arm 0 engaged by the roll-back d; into the hub of this rollback enters the square spindle e of the door handle f. This door handle is formed with a ball 9 which is locked into the escutcheon an outer cup 8 and an inner'cup h by spinning down the outer sleeve end z' of the hub of the escutcheon. This is only one form of a coupling between the handle and the escutcheon that may be used. There are several other desirable forms of coupling up the escutcheon with the handle so that the handle has the bearing in the escutcheon plate, but still has a limited universal movement in such bearing to permit the escutcheon plate to accommodate itself to the outer surface of the door and to permit the end of the handle spindle to be inierltied into the hub of the roll-back of the Obviously, when the escutcheon is secured to the door by screws, the door handle can be permanently coupled to the roll-back by simply inserting same in the roll-back.

However, if the bolt is in any way arrestedbefore its outward limit of projection is reachedit will be clear that the arin 0 will not engage against the roll back b. The result will be that this roll-back is free to chatter between the arm 0 and its stop 3 hub, also between t e roll-back and its stop and the bolt arm. This we accomplish by insertin a coil spring in the door handle spindle ole, anchoring one end to the door and the other end to the spindle. However, this anchorin arrangement could not be very easily an quickly done were it not for the special form of fitting that we have designed to accomplish the anchoring to the door and the coupling to the spring.

A pair of telescoping cups are rovided; he outer cup has a large round centra opening t, through which the square s indle e can pass freely. The inner cup which is clamped rotatably to the outer telescoping cup by the anchored in the inner cup. The spring is under no strain when the cup is fitted tightly into the counterbore n. The counterbore is of such a size that the cup has to be forced into the counterbore and consequently the outer cup becomes anchored by the friction in the door stile.

All that is necessary in assembling the handle is to thread the spindle through the squared opening of the inner cupor the cup that we may call the rotating'cup. The door handle then may be turned as many quarter turns as is necessary toget the desired strength of spring stress. The door handle spindle is then threaded through the square hol in the roll-back and obviously, this roll-book i placed under spring stress, driving it either against its stop 3 or the bolt arm 0, depending upon which direction the door handle has been turned in putting the coil spring under stress.- This will obviously take up not only any looseness between the roll-back and the bolt arm and the roll-back stop, but also any looseness between the spindle and the roll-back hub, making a perfect, anti-rattling device which may be installed in the job as a unit assembly, by simply driving it into the counterbored opening in the door stile or the lockboard.

What we claim is:

1. Th combination of a door having a lock board and provided with an opening thereinto, a lock secured on the inside of the door and having a roll-back with a prismatic opening, a door handle provided with a horizontal prismatic spindle passing through said opening and arranged to engage 1n the prismatic opening of the rollback, and an anti-rattling device fitted into the opening cut into the door and having two members relatively rotatable with a spring resistance to such rotation, whereby the handl spindle may be engaged with one of these members and rotated before it is inserted into the opening in the roll-back to thereby put the handle spindle and the roll-back under a yielding stress.

' 2. The combination of a door lock provided with a roll-back, an outside door handle provided with a spindle which can be detachably engaged with the roll-back, and an anti-rattling device threaded onto the spindle and comprising a pair of relatively rotatable members resisted by a spring resistance, whereby one of the members can be anchored to the door and the other member to the door handle spindle, and the door handle spindle be turned before it is engaged with the roll-back for the purpose of putting the roll-back and handle under yielding stress.

3. The combination of a lock with a rollback, an outside door handle provided with a spindle arranged to be detachably en aged with the roll-back, an anti-rattling evice comprising a pair of telescoping cups, one rotatable within the other against the resistance of a spring, whereby the outside cup may be fitted into the mortise of the doorto anchor one end of the spring and the other cup may be threaded non-rotatably onto the door handle spindle to permit the spindle to be turned before the spindle is threaded into the hole in the roll-back, thereby to place both the roll-back and the spindle under yielding tress.

In testimony whereof we affix our signatures.
